ArrayIndexOutOfBoundException 删除单条记录

Question

我正在使用带有预填充数据的外部数据库。用户还可以在该数据库中执行 CRUD 操作。但是，当我删除记录时，它会抛出 Array out of bound 异常。这是我为删除记录而实施的代码片段。

String part[] = ((ItemModel) parent.getItemAtPosition(position)).getName().split("-");
String childQuery = "delete from Stock where item_id = (select id from Item where name = '" + part[0].trim() + "' and size = " + part[1].trim() + ")";
DBHelper.execute(childQuery);
String deleteQuery = "delete from Item where name  = '" + part[0].trim() + "' and size = " + part[1].trim() + " ";
DBHelper.execute(deleteQuery);
customAdapter.notifyDataSetChanged();
dismiss();

try {
    if (!TextUtils.isEmpty(InOutStockActivity.etInOutName.getText().toString())) {
        InOutStockActivity.etInOutName.setText("");
    }

    if (!TextUtils.isEmpty(TotalStockActivity.etTotalName.getText().toString())) {
        TotalStockActivity.etTotalName.setText("");
    }
} catch (NullPointerException e) {
    e.printStackTrace();
}
TastyToast.makeText(mContext, "Record Deleted Successfully.", TastyToast.LENGTH_LONG, TastyToast.DEFAULT);

这里是我的 logcat 错误。

java.lang.ArrayIndexOutOfBoundsException: length=1; index=1

name 不包含“-”，但您的代码假定包含“-”。
